raised the pressure of the oil opens this valve to allow the oil to be thrown out of the spout, and as soon as this pressure is removed by the piston being lowered the spring N closes the valve M automatically and cuts off further flow of oil. 7

It will be seen from the foregoing that by one movement of the thumb the oil is forced or thrown from the spout of the can when held in any position, thus enabling the operator to oil machinery overhead, near walls, floors, posts, 850., at any point or place where the spout of the can will reach. The oil can be thus thrown when chilled so that it will not flow from an ordinary can, thus avoiding delay in warming the oil. The oil is delivered only at the will of the operator, thus avoiding the oil being wasted by being spilled in places where it is not needed.

By the use of ourimproved oiler a considerable saving in both oil and time employed is effected, as no oil is wasted, and timeis saved, as the operator does not have to adjust his can or person to the peculiar positions required in oiling intricate machinery with a common oil-can where the oil runs by gravity. The oiler can thus be used with great convenience.

Our improved oiler is simple, strong, and cheap in construction, and exceedingly efficient in its operation.

SPECIFICATION forming part of Letters Patent No. 360,746, dated April 5, 188/.

Application filed August 27, 1886. Serial No. 212,017. (No model.)

To aZZ whom it may concern.-

Be it known that we, THOMAS BERTRAND WILKINSON and J AMES LYMAN CUTLER, of Arcadia, in the county of Crawford and State of Kansas, have invented a new and useful Improvement in Oilers, ofwhich-the following is a specification.

Our invention consists in an improved oiler, which possesses superior advantages in the points of efficiency in operation, economy in time and oil employed, and convenience in use, and which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, 1 5 Figure l is a perspective view of our improved oiler, and Fig. 2 is a vertical sectional view of --the same, taken on liner 1", Fig. 1. Fig. 3 is a sectional'view of the outer end of the spout. The same letters of reference indicate cor- 2o responding parts in all the figures.

Referring to the several parts by letter, A represents the body of the oil-can, which is of the usual form, being provided with the handle B and the spout O, the exterior part of which 2 is of the usual construction.

Vithin the body A is secured, at that side of the can opposite to the handle B, the pumpbarrel or vertical cylinder D, the lower open end of which extends down within close prox- 0 imity to the bottom of the can, which insures the working of the oiler as long as thereis any oil within the can. Thelowcr end ofthe spent 0 communicates below the top of the can with the upper part of this cylinder D, as shownin the sectional view, Fig. 2, of the drawings. \Vithin this pump barrel or cylinder D works the piston E, which is formed with the upwardly-opening valves F, which admit the oil within the cylinder D as the piston moves 4o downward and which close on the upstroke ofthe piston, the lower end of the pump-barrel being provided with the usual inwardlyopening Valve D, which works reversely to the valve in the piston, opening on the up- 5 stroke of the piston to admit oil into the cylinder, and closing as the piston descends to pre vent the oil drawn into the cylinder on the upstroke of the piston from flowing out on the downstroke of the same, thus serving to keep the cylinder full at all times.

I-I indicates the piston-rod or connectingrod, which connects the'piston with the operating thumb-lever J, the piston-rod extending up through the top ofthe cylinder and through a stuffing-box, I, on the top of the can-body, as shown. The upper end of this rod is then pivoted to the forward end of the thumb-lever J, which is centrally pivoted on the top of the can-body in bearings K, and has its rear end flattened to form a convenient bearing for the So thumb of the operator. A spring, L, is arranged, as shown, beneath the free end of this lever, and serves to normally hold the forward end of the lever, which is pivoted to the upper end ofthe piston-rod, in its lowermost position. 6 The lever Jis so arranged on the top of the can that its free end is within convenient reach of the thumb of the operator when that hand is grasping the handle of the can.

In operation, in order to discharge the oil from the oiler at that part of the machinery at which the nozzle of the spout is being held, the operator presses down the free end of the lever J with the thumb of the hand which is grasping the handle of the oiler, thereby raising the piston in the cylinder within the canbody, and thus discharging the oil at that moment contained in the cylinder D up and, out through the spout C, which, as shown, communicates with the upper part of the cylin- S 3 der D. The moment the pressure of the thumb is removed from the free end of the lever J the spring L raises the said free end, thereby forcing down the other end of the lever, and through the connecting or piston rod lowering the piston in the cylinder D, the valves of the piston opening up asit is thus lowered and closing when the piston reaches the lower end of the cylinder.

\Vhen the oil is very warm some small quan- 9o tity of it might escape from the nozzle when the can is held nearly upside down, as is sometimes necessary. In order to obviate this objection we place within the spout, about four inches from the nozzle, just where the crook 5 in the spout begins, an upwardly-opening valve, M, which is normally held closedby the spring N, of suitable form, thus effectually preventing any oil from escaping from the spout by gravity, and as soon as the piston is I03
